Specification of Letters Patent.

Patented June 25, 1907.

Application filed February 20,1907. Serial No. 358,428.

To all whom it may concern:

Be it known that I, JAMES M. BOYLE, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a certain new and useful Improvement in Means and Methodsfor Continuously Making Tube- Lined Monolithic Hollow Objects, of whichthe following is a specification.

The invention relates to monolithic cement hollow objects havinginserted tubular linings, and consists in the means and methodhereinafter set forth for continuously and progressivelymaking a tubelined monolithic cement conduit.

In the accompanying drawings-Figure 1 is a vertical section on the line90 a: Fig. 2, showing the apparatus in place in the trench, andillustrating the mode of putting together the tube sections which areembedded in the cement conduit. Fig. 2 is plan view and partial sectionon the line 3 y of Fig. 1.

Similar numbers of reference indicate like parts.

1 is a trench in which may be embedded the usual mold boards 2, whichreceive be tween them the deposited plastic material.

3 is a receptacle including a hopper portion, the front wall 4 of whichextends to the bottom of the mold. The rear wall 5 has a horizontalflange 6, the purpose of which is to determine the de th of thedeposited material and to smoot the upper surface thereof.

In front of the hopper wall 4 may be se,

cured the slide like former 7, having side pieces and a cross piece 9.Passing through the cross piece 9 and through the Wall 4 and securedtherein in anysuitable wayis a metal tube 10, or as shown a plurality ofsuch tubes, which may, for example, as here shown,

be arranged in two groups of three each.

The receptacle 3 is supported on trucks 11 j ournaled in suitablebrackets 12, which run upon the edges of the mold.

The apparatus is drawn forward by a cord or wire 13 attached to thereceptacle, or by cords or wires 14 attached to the former, or by both,as desired, said cord or cords being taken to any suitable stationarywinding device, not shown.

I may dispense with the mold boards 2 and deposit the plastic materialdirectly in the trench, in which case the side pieces of the former 7serve to smooth the vertical surfaces of said trench, as fully explainedin another application for Letters Patent, Serial N 0. 358,428 filed byme simultaneously herewith. The operation of the device is as follows:The receptacle 3, dotted lines Fig. 1, being brought to the end of themold or trench from which work is to begin, a section A (or two or moreconnected sections A, B of pipe which is to form the tubular lining ofthe conduit is introduced through a guide tube 10 and held in positionby any suitable means, as by passing through an end cross wall 15. Theplastic material is then shoveled into the hopper while the receptacle 3is continuously drawn forward by the cords or wires 13, 14. The materialthen fills the trench or mold until it reaches the flange 6, which, asbefore stated, thus limits its depth and smooths the upper surface.Before the receptacle reaches the end of the inserted, or last inserted,tube section, a tube section O is connected by any suitable union 16,and then another section D, and so on. The workman in the drawing isrepresented as connecting section D to section O. Where there are anumber of inserted tubes the unions or joints are preferably placedstaggered as, shown in Fig. 1.

The inserted tube sections may be of any suitable material such asindia-rubber, guttapercha or the various known insulating compounds.

By the foregoing device I am enabled rapidly to make tube lined cementconduits continuously in the place where they are'to remain.

I claim 1. A stationary open mold, a tube supported in fixed positiontherein, a device for depositing plastic material in said mold to embedsaid tube and means for continuously moving said device along the lengthof said mold.

2. A stationary open mold, a plurality of parallel tubes supported infixed osition therein, a device for depositing plastlc material in saidmold to embed said tubes and means for continuously moving said devicealong the length of said mold.

3. The method of making tube-lined cement conduits which consists incontinuously and progressively depositing plastic material in an openstationary mold upon a fixed lining tube supported in said mold.
